DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1, refer to Figure 1-Figure 8 A constant force rolling massage device comprises a barrel cover 1 and a barrel body 3, both ends of the barrel body 3 are fixedly connected with side plates 2, a plurality of bone-shaped guide rails 5 and a drive chain 7 distributed in a circumferential array are arranged inside the barrel cover 1, and further comprises: A driving assembly 4, which is fixedly connected to the bone-shaped guide rail 5, and includes a motor 41, a driven gear 43 and a driving gear 45; A constant force tensioning assembly 6, which is fixedly connected to the bone-shaped guide rail 5, and includes a massage rubber wheel 61 and a pressure sensor 64; The lubrication assembly 9 is located on one side of the bone-shaped guide rail 5 . The lubrication assembly 9 includes a lifting plate 91 , a piston rod 92 and a transfer frame 95 . A fixing cylinder 94 is provided inside the transfer frame 95 . The fixing cylinder 94 is connected to a reset spring 93 and a piston plate 98 .

[0020] Furthermore, the side plate 2 is fixedly connected to the cylinder cover 1, the cylinder cover 1 is located outside the cylinder body 3, the cylinder cover 1 is cylindrical, and the cylinder body 3 is truncated cone-shaped.

[0021] It should be noted that: the inner diameter of the cylinder 3 is large at one end and small at the other end. When in use, the arm can be inserted from the smaller end. The advantage of this setting is that it can better fit the arm and avoid the device falling off due to the same and too large inner diameter. In addition, the side panel 2 and the cylinder cover 1 can be made of plastic, which is not only wear-resistant, but also helps to protect the device as a whole and reduce damage caused by falling. The cylinder 3 is made of soft material to avoid damage to human skin, while improving comfort and facilitating the subsequent movement of the massage rubber wheel 61. In addition, the side panel 2 is detachably connected to the cylinder cover 1 and the cylinder 3, which makes it easy to inspect and replace the parts inside the cylinder cover 1.

[0022] Reference Figure 2-Figure 6 , further; the constant force tensioning assembly 6 also includes an electric telescopic rod 65, one end of the electric telescopic rod 65 is fixedly connected to the pressure sensor 64, the pressure sensor 64 is fixedly connected to the side wall of the bone-shaped guide rail 5, and the other end of the electric telescopic rod 65 is fixedly connected to a fixing seat 62, the fixing seat 62 is rotatably connected to the massage rubber wheel 61, and the inner wall of the massage rubber wheel 61 is fixedly connected to a plurality of teeth 66 distributed in a circumferential array, and the teeth 66 are meshed with the drive chain 7; the constant force tensioning assembly 6 also includes a telescopic spring 63, the telescopic spring 63 is sleeved on the outside of the pressure sensor 64 and the electric telescopic rod 65, and the two ends of the telescopic spring 63 are respectively fixedly connected to the side wall of the bone-shaped guide rail 5 and the side wall of the fixing seat 62.

[0023] It should be noted that: after the user wears the body device, as the barrel cover 1 and the barrel body 3 move back and forth on the arm, the massage rubber wheel 61 will be squeezed to different degrees due to the different thicknesses of various parts of the arm. When the massage rubber wheel 61 is subjected to pressure, pressure will be applied to the pressure sensor 64 through the electric telescopic rod 65 on one side of the fixing seat 62. The pressure sensor 64 is electrically connected to the electric telescopic rod 65. When the pressure sensor 64 detects pressure, the moving end of the electric telescopic rod 65 will be contracted. The specific degree of contraction depends on the signal value detected by the pressure sensor 64. When there is no pressure on the pressure sensor 64, the electric telescopic rod 65 is reset. Therefore, the feedback signal of the pressure sensor 64 at different positions is used to adjust the distance between the massage rubber wheel 61 and the arm in real time. By continuously adjusting the massage rubber wheel 61, the massage effect always maintains a constant pressure, thereby imitating the massage trajectory of the human hand and improving the massage efficiency. Moreover, the sizes of the various massage rubber wheels 61 are the same, and the massage rubber wheels 61 are made of rubber material to provide good comfort, thereby improving the comfort during the massage process.

[0024] Furthermore; the driving assembly 4 also includes a support seat 1 42 and a support seat 2 44, which are respectively fixedly connected to the side walls of the bone-shaped guide rail 5, the support seat 1 42 is rotatably connected to the driven gear 43, the support seat 2 44 is rotatably connected to the driving gear 45, the side wall of the support seat 2 44 is fixedly connected to the motor 41, the motor 41 is transmission-connected to the driving gear 45, and the driving gear 45 and the driven gear 43 are both meshingly connected to the drive chain 7.

[0025] It should be noted that: during the operation of the constant force tensioning assembly 6, the motor 41 is started at the same time, and the motor 41 is connected to the driving gear 45 through a bevel gear. When the motor 41 drives the driving gear 45 to rotate, due to the meshing connection between the driving gear 45 and the drive chain 7, and the meshing connection between the drive chain 7 and the driven gear 43 and the teeth 66, the teeth 66 will drive the multiple massage rubber wheels 61 to rotate synchronously, so as to realize the self-rotation of the massage rubber wheels 61. Through the cyclic rotation of multiple annularly distributed massage rubber wheels 61, the arm can be subjected to all-round and precise pressing massage.

[0026] Example 2, refer to Figure 7-Figure 8 , further; the two ends of the bone-shaped guide rail 5 are respectively fixedly connected to the side walls of the two side panels 2, a liquid storage chamber 52 is opened inside the bone-shaped guide rail 5, and a liquid filling port 51 is provided on the side wall of the bone-shaped guide rail 5. The liquid filling port 51 is connected to the liquid storage chamber 52, and the lower side wall of the bone-shaped guide rail 5 is fixedly connected to a fixed tube 8, and one end of the fixed tube 8 is connected to the inner wall of the liquid storage chamber 52; the adapter frame 95 is fixedly connected to the end of the fixed tube 8 away from the bone-shaped guide rail 5, and the adapter frame 95 is located on the inner side of one of the massage rubber wheels 61. The side wall of the adapter frame 95 is fixedly connected to the fixed cylinder 94, and one end of the fixed cylinder 94 is provided with a drainage slot 97. The side of the fixed cylinder 94 The wall is provided with a number of through holes 96 distributed in a circular array; the inner wall of the fixed cylinder 94 is slidably connected to the piston plate 98, the piston plate 98 is located below the through hole 96, the outer diameter of the piston plate 98 is larger than the inner diameter of the drainage slot 97, the side wall of the piston plate 98 is fixedly connected to one end of the piston rod 92, the piston rod 92 is slidably connected to the side wall of the fixed cylinder 94, and the piston rod 92 is arranged in a "T" shape; the return spring 93 is sleeved on the outer wall of the piston rod 92, the two ends of the return spring 93 are respectively fixedly connected to the side wall of the piston rod 92 and the side wall of the fixed cylinder 94, and the end of the piston rod 92 away from the piston plate 98 is fixedly connected to the lifting plate 91.

[0027] It should be noted that: in the process of the tube cover 1 driving the bone-shaped guide rail 5 to reciprocate, due to the different thicknesses of the arms, some areas will squeeze the massage rubber wheel 61 respectively, and because lubricating oil is added to the inside of the liquid storage chamber 52 through the liquid filling port 51 in the initial state, the lubricating oil fills the liquid storage chamber 52 and flows into the inside of the adapter frame 95 through the fixed tube 8. When one of the massage rubber wheels 61 contracts through the pressure sensor 64 and the electric telescopic rod 65, it will gradually squeeze the lifting plate 91, so that the lifting plate 91 drives the piston rod 92 to move toward the side of the bone-shaped guide rail 5, and as the piston rod 92 moves upward, it simultaneously drives the piston plate 98 to move, so that the piston plate 98 no longer blocks the drainage slot 97, and in the process of the piston plate 98 moving upward, the lubricating liquid will enter the inside of the fixed tube 94 through the through hole 96, and then drip from the drainage slot 97 to the surface of the teeth 66 and part of the drive chain 7, and lubricate the entire drive chain 7 through the rotation of the teeth 66 and the drive chain 7 itself. The drive chain 7 is made of metal, so the wear of the drive chain 7 and the corresponding parts can be reduced, the service life can be guaranteed, the later disassembly and maintenance can be reduced, and the normal operation of the equipment can be guaranteed. Even if there is a bone-shaped guide rail 5 below, the lubricating liquid will be discharged due to the vibration during the movement, and the cylinder body 3 can be rotated each time it is used. On the one hand, it is to better massage different parts, and on the other hand, it can also better lubricate the drive chain 7 and reduce wear. When the massage rubber wheel 61 is reset, the piston plate 98 re-blocks the drainage slot 97 to avoid waste caused by continuous dripping and accumulation of liquid inside the cylinder cover 1. In addition, the bone-shaped guide rail 5 is made of ABS material. ABS plastic has good strength and toughness, can withstand certain impacts and loads, has strong impact resistance, and can maintain structural integrity even under large external forces. Moreover, ABS plastic has good chemical resistance and can resist the erosion of some chemicals. It has strong acid and alkali corrosion resistance, is not easily corroded by chemical substances, and maintains a smooth surface.

[0028] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
